A friend was given a Trek single track 8200 MTB with an aluminum frame. He wanted to clean it up and ride it but the chainstays and seatstays are offset to the right about an inch. The rear tire seats all the way to the rear of the dropouts and ends up being uncentered in the frame. It seems to ride ok but he thinks that the frame might be bent and is worried about it breaking under hiim in the hills.
I think he's right about it being bent but I thought I would check here to make sure that offset thing isn't some design we've never heard of.
What do you think?
